The new chicken models in 1.21.70.22 do not have the same wing pivot positions as Java Edition. This report is the Bedrock equivalent of MC-215559.

This affects the chicken.v2.geo.json and chicken.cold.geo.json files from the Drop 1 2025 resources.

A sample pack with corrected chicken models is attached to this report.

Current Bedrock Configuration

Java-Equivalent Configuration

Expected Result

Chickens have the same pivot points for all bones as Java Edition.

Observed Result

Chicken wing0 and wing1 bones have different pivot points than Java Edition.

To Fix

Change the "pivot" x values from ±3 to ±4 on each wing bone.

Here is a sample resource pack which fixes the wing pivot positions (and fixes chicken body rotation, MCPE-190396): new_chicken_model_fix.mcpack
